+	help
+	  If you say Y here, then the MLD Snooping Querier will be built
+	  with a per bridge port wake-up call "feature"/workaround.
+
+	  Currently there are mobile devices (e.g. Android) which are not able
+	  to receive and respond to MLD Queries reliably because the Wifi driver
+	  filters a lot of ICMPv6 when the device is asleep - including MLD.
+	  This in turn breaks IPv6 communication when MLD Snooping is enabled.
+	  However there is one ICMPv6 type which is allowed to pass and
+	  which can be used to wake up the mobile device: ICMPv6 Echo Requests.
+
+	  If this bridge is the selected MLD Querier then setting
+	  "multicast_wakeupcall" to a number n greater than 0 will send n
+	  ICMPv6 Echo Requests to each host behind this port to wake them up
+	  with each MLD Query. Upon receiving a matching ICMPv6 Echo Reply
+	  an MLD Query with a unicast ethernet destination will be sent to the
+	  specific host(s).
+
+	  Say N to exclude this support and reduce the binary size.
+
+	  If unsure, say N.
